Title: Optical reflecting plate
Inventor: YAMADA AKIRA
IPC: G02B5/08
Filed: 1989-04-19
Abstract: PURPOSE:To obtain the reflecting plate which is free from a change in reflecting efficiency with age by epitaxially forming an Al thin film on a single crystal substrate and coating the film with a protective permeable film of Al thin film having the less light absorption. CONSTITUTION:The Al thin film is epitaxially formed on the single crystal substrate and is coated with the protective permeable film having the less light absorption of the Al thin film. Namely, the Si substrate is cleaned by an org. solvent, such as acetone, trichloroethylene or fluorocarbon 113 or the like and thereafter, the substrate is immersed in a soln. mixture composed of sulfuric acid and hydrogen peroxide to form the thin oxide film on the surface of the Si substrate. After this dip processing is repeated several times, the substrate is dried and is put into a vacuum chamber where the substrate is heated to about 800 deg.C to remove the thin oxide layer and to form the clean surface so as to be ready to vapor deposition. The Si (111) single crystal substrate is then irradiated with Al cluster ions thereon by a cluster ion beam method to epitaxially grow and form the Al (111) single crystal film. Finally, the surface of the Al (111) single crystal film is coated with the protective film consisting of MgF2. The optical reflecting film which is not changed with age and is not deteriorated in reflection efficiency is obtd. in this way.
